In this chapter, you'll learn how create and execute custom scripts from Medusa's CLI tool.

## What is a Custom CLI Script?

A custom CLI script is a function to execute through Medusa's CLI tool. This is useful when creating custom Medusa tooling to run through the CLI.

## How to Create a Custom CLI Script?

To create a custom CLI script, create a TypeScript or JavaScript file under the `src/scripts` directory. The file must default export a function.

For example, create the file `src/scripts/my-script.ts` with the following content:

```ts title="src/scripts/my-script.ts"
import { 
  ExecArgs,
  IProductModuleService,
} from "@medusajs/types"
import { Modules } from "@medusajs/utils"

export default async function myScript({ container }: ExecArgs) {
  const productModuleService: IProductModuleService = container.resolve(
    Modules.PRODUCT
  )

  const [, count] = await productModuleService
    .listAndCountProducts()

  console.log(`You have ${count} product(s)`)
}
```

The function receives as a parameter an object having a `container` property, which is an instance of the Medusa Container. Use it to resolve resources in your Medusa application.

## How to Run Custom CLI Script?

To run the custom CLI script, run the Medusa CLI's `exec` command:

```bash
npx medusa exec ./src/scripts/my-script.ts
```

---

## Custom CLI Script Arguments

Your script can accept arguments from the command line. Arguments are passed to the function's object parameter in the `args` property.

For example:

```ts
import { ExecArgs } from "@medusajs/types"

export default async function myScript({ args }: ExecArgs) {
  console.log(`The arguments you passed: ${args}`)
}
```

Then, pass the arguments in the `exec` command after the file path:

```bash
npx medusa exec ./src/scripts/my-script.ts arg1 arg2
```
